Title: Improvements in metal crates for bottles and the like
IPC: B65D85/30
Filed: 1935-09-04
Abstract: 462,134. Metal bottle &c. crates. BRITISH LIGHT STEEL PRESSINGS, Ltd., BLANCH, S. F., and WILD, J. H. Sept. 4, 1935, No. 24616. [Class 18] A non-corroding metal crate for beerbottles, munitions &c. of cylindrical form, built from light steel pressings or strips and having two or more parallel runners or shoes on the bottom to facilitate transport and to co-operate with the top of a second crate for nesting, is built up from U-shaped steel strips 10-14-10 and 10-15-10, Fig. 1, the parts 14, 15 of which cross and constitute the crate bottom, while the parts 10 constitute the four walls. The uprights 10 are embraced by straps 11, 12, 13, the points at which the strips cross being spot-welded. The crosssection of the strips is of part-circular shape as shown to the left of Fig. 1. Runners 29 of channel section are welded to the front and rear members 14, the length being such that they fit within the mouth of a crate placed underneath for stacking. Hand-holes A, Fig. 2, are formed at the ends by using short uprights 10, and a bar 28, Fig. 1, of semicircular section is welded to plates 27 welded to straps 11, 12. This handle may, alternatively, have end palms welded to the straps 11, 12, 13, so as to incorporate the handle in the structure of the crate. The bottles &c. are spaced apart by two grids supported from angle members 32, 33 spot welded to straps 12, 13 and consisting of crossed wires 34, Fig. 3, connected by rectangular pieces 35 the edges of which are turned downwardly and inwardly. Loops 38, Fig. 1, on the wires 34 support the bottles laterally. In the alternative form shown in Fig. 5, a thin sheet steel blank is pressed to form two long sides 40, a bottom 49, and parts 50, 51 of the ends, top members 53 of the ends being added by welding the lower edges 43 of which are beaded to form handles. The corners of the crate are rounded. The bottom has inwardly projecting annular indentations which locate the bottle bottoms, the central portion being removed if desired. A tray 44 with flanged apertures is secured removably or by welding or riveting its flange 45 within the crate. Runners 46 are fitted to the bottom and, when a lid 47, Fig. 1, is fitted, this is correspondingly indented. When a lid is not employed, manipulating bars similar to those shown at 28, Fig. 1, may be fitted. The edge of the mouth may be beaded, and a strengthening indentation 52 may be pressed in the sides and ends. For bottles with concave bottoms, conical projections may be formed on the base to fit into the bottoms. For reducing weight, flanged holes may be formed in the long sides and in the lid. Drainage holes may be formed in the bottom. According to the Provisional Specification, a removable lid may be employed.

Abstract: 1,263,624. Matching impedances. TAVKOZLESI KUTATO INTEZET. 14 May, 1969 [15 May, 1968], No. 24679/69. Heading H1W. [Also in Division G1] A microwave signal detector for measuring the signal power in a coaxial line by converting the signal to a direct current comprises a first, central, conductor 6, second, third and fourth conductors 9, 8, 11 coaxial with and surrounding the first conductor, a connecting element 4 for connecting the first and second conductors, which together form an inner coaxial line, to the line carrying the signal to be measured, a diode 5 arranged within the inner coaxial line with one electrode connected to the first conductor 6, and a metal disc 7 connecting the other diode electrode to the third conductor 8, the disc being spaced from the second conductor 9 by an axial gap which is a small fraction of a wavelength at the centre frequency of the operating frequency range of detector. The disc constitutes a short circuit to microwave frequencies but not to D.C. A further metal disc 12 interconnects the second and fourth conductors but is axially spaced from the third conductor. Dielectric 10 spaces the second and third conductors so that the two form a middle coaxial line whose characteristic impedance is a small fraction of that of the inner coaxial line and whose length is about a quarter wavelength at the centre frequency. The third and fourth conductors constitute an outer coaxial line whose characteristic impedance is about ten times that of the middle coaxial line. To reduce microwave radiation, a microwave damping material, e.g. ferrite, is placed in the outer coaxial line, and the fourth conductor 11 is extended axially and closed by a metal disc 13 to form a cavity 14 whose resonant frequency, in any oscillating mode, is outside the operating frequency range of the detector. The cavity may accommodate resistor(s) which form part of the detector circuit. To improve matching, the characteristic impedance of the inner coaxialline (formed by conductors 6, 9) equals the real part of the diode forward impedance, and a short tube 14 of iron or ferrite powder is disposed between conductors 6, 9. Electrical contact between the diode 5 and the disc 7 is maintained under pressure by means of a split conical bush compressed into a conical hole in the disc 7 by the tightening of a nut (not indicated).

Title: Improvements in or relating to a brush-making machine
IPC: A46D3/04
Filed: 1951-10-25
Abstract: 699,327. Brush making machines. CARLSON TOOL & MACHINE CO. Oct. 25, 1951 [March 27, 1951], No. 24961/51. Class 19. [Also in Group XXX] A brush making machine includes a reciprocable picker bar movable from a bristle receiving point to a delivering point, a magazine for feeding bristles to the bar having two stock boxes and movable to position either box at the receiving point, and means for stripping excess bristle from the bar and positioned in whichever box is located at the receiving point. The machine described is applicable to making brushes having nylon tufts surrounded by a rim of stiffer and smaller tufts. The bristles are contained respectively in the two compartments of a magazine pivoted at its upper end 44 and moved by means of an air pressure operated piston, Fig. 1 (not shown), to position the lower end of either box at the receiving point (e.g. the left hand box as shown). The bristles are urged downwards by weights 65 and are held in position by the adjustable backs 58 of the boxes. The picker bar comprises a notch 15 formed by the gap in two members 13, 14 held by a tie bar 16 and movable to the right to the delivering or tufting point 37. The effective depth of the notch is determined by a forked bar 19 the tines of which pass each side of the notch and open out at the delivery point. This bar is attached to a vertical slide 23 which may be moved up and down by a crank 32 linked to the magazine so that as the latter swings from one position to the other the depth of the notch and thus the size of the tuft is simultaneously changed, screws being provided to adjust the effective size of each notch. A stripper bar 70 having a nose 72 resting close to the notch serves to remove surplus bristles from the notch when it is moved to the delivering point, the slanting edge urging such bristles back into the box. The central partitions 51, 52 of the magazine are lifted by the nose when the magazine swings to the right and falls when it swings to the left. In the position of the magazine shown the stripper bar lifts the bristles in the right hand box away from the picker bar while a forked bar 74 lifts the bristles in the left hand box when the magazine is swung to the left.

Patent GB-822739-A (GB)
Title: Improvements relating to the production of hard and flexible microcrystalline waxes
Inventor: COLLIER ALAN
IPC: C10G73/42
Filed: 1956-08-16
Abstract: A single-stage solvent recrystallized bright stock slack wax feedstock is separated into hard and flexible waxes by dissolving the feedstock in a water-saturated wax solvent, adding solid urea and agitating at an elevated temperature to cause the straight-chain hydrocarbons in the wax to form an adduct with the urea, separating the adduct by filtration, and recovering flexible wax from the filtrate and hard wax from the adduct.  The preferred wax solvent is methyl iso-butyl ketone which may be water-saturated by storing it over water.  The separated adduct is preferably washed with fresh solvent and then decomposed with boiling water which dissolves the urea and leaves the wax in solution in the occluded wash solvent. The preferred wax:solvent ratio is between 1 : 5 and 1 : 10 gm/ml. and the urea is preferably added in amounts between 0.25 and 3 parts by weight of urea per part of wax.  The agitation of the dissolved feedstock and the urea is preferably conducted at 160-170 DEG  F. for 20 minutes.  A hard wax is defined as having a penetration of less than 15 mm/10 and a flexible wax as being capable of flexing (as a 1/4 X 1/3 inch strip) through 70 DEG  C. at least 20 times at 0 DEG C.

Title: Improvements in or relating to photophonographic methods of sound recording and reproducing
IPC: G11B7/28
Filed: 1927-09-23
Abstract: 306,565. Eldred, B. E. Sept. 23, 1927. Optical records and apparatus. - An optically condensed photographic sound record is produced by optically reducing and projecting a master film, and reproduction is effected by optically enlarging and projecting the record. This reduced record can be made on a film of slower speed and finer grain owing to the concentration of the light, and enables a substantially long play or speaking books to be produced from shorter lengths of film. Fig. 2 shows a method of making a condensed record on a film 13 by reduced copying of a master record 9, which may be oversized. The record 9 is drawn across an apertured plate 8 by rolls 17 which drive the film 13 at the desired reduced speed by belts 16 and rolls 15. Light from a source 6 is directed through a concentrating lens 7 and passes through the film 9 and through a reducing lens 10 directing it on to the film 13 with the desired reduction, the films being arranged at the conjugate foci of the lens 10. Alternatively the film 13 may be driven in the same direction as the film 9 by leading it over guide rolls and over the roll 14 attached to the roll 17 driving the film 9. In reproducing from the condensed record or a copy thereof, light is directed through the record and is projected by an enlarging lens on to light-sensitive cell.
